 In recent years, there has been a shortage of skill workers and engineers to serve in the construction industry. This has made it essential to train new tradesmen and engineers efficiently and in a short time. The most effective approach for new trainees in the construction industry is to use full-size construction models, in addition to their regular classroom education.<br> Two-dimensional drawings have been the heart of the printed materials used in the practical curriculum, but new trainees have found them difficult to read. Most of the trainees are unable to visualize the completed structure in 3 dimensions in their minds by looking at the 2-dimensional drawings (floor plans, elevations, and sectional plans). This has, in turn, blocked them from gaining the capabilities and the skills that they need.<br> As a solution to these issues, we have developed a software-based text that is easier for new trainees to understand. The students learn to correctly draw a rebar arrangement and a rebar bending schedule. Augmented reality technology has been implemented to extract 3-dimensional images from 2-dimensional drawings. These materials together are designated the “group of new educational materials” and are coded to be used on smartphones, and then build a 3-dimensional model showing the actual shape of a completed rebar cage. This is then disassembled, and assembly procedure diagrams and an assembly procedure video are created.<br> An experiment in the assembly of rebar was performed using new trainees as subjects in order to validate the group of new educational materials. The time required to assemble the rebar by the subjects using the new educational materials was reduced by 35% in comparison to the group of students who did not use the materials. This confirmed that the new educational materials are effective for instruction of new trainees.
